[Q] SD Card read issues in programs - EVO 4G Q&A, Help & Troubleshooting

My SD card started acting up lately. I do not know what could have caused it but it seems to just be running incredibly slow for read speeds. When I turn on my phone it does say mounting storage card or whatever at the top and it mounts and I can see it in root explorer as well as all of my documents on the card, my beautiful widgets homescreen skin loads without problems and I can take pictures that save to my sd card. However, almost no program that uses the SD card can read from it succesfully. The gallery shows no pictures and simply says loading, even though I have multiple pictures on there and just took some with the camera app. The music program claims I have no music even though I have thousands of songs. My scorecenter app does not remember any of my favorite teams that are stored on the SD card.
I am on CM7 nightly build 23 right now, but this problem began a few days ago when I was on MIUI 3.05. I have a 16gb class 2 card that was working fine a few weeks ago, and I flashed CM7 thinking it might be my MIUI rom but the problem persists. I can still boot into recovery, see my SD card and load custom roms from it.
I attempted formatting the SD card through android (clear storage in storage settings) but the problem persists.
Is my SD card dying?
edit: write speeds are terribly slow as well. a 200mb file transferring right now looks like it will take about 30 minutes to complete. That's definitely not usual. Do you think this would be my sd card, or my phone? I'll have to try the card out in another phone or sd card reader. in the meantime any suggestions would still be appreciated

[Q] Apps on SD Card Not Launching

I'm running Myn's Warm 2.2 RLS 4. I rebooted my phone this morning and ever since none of the apps located on the SD card will launch. I can browse the SD card using Astro, I can play music stored on the SD card, and I can browse pictures on the SD card, but none of the apps on the card are populating the app drawer or creating their icons on my desktop.
And to make it worse, I got my Swype beta email today and I can't install it because it needs access to the SD card. I swapped in my old 8GB one (current one is 16GB) and I was able to install Swype.
The card works fine in the computer. I'd really like to avoid having to reformat the card if I can help it.
My only suggestion would be to try moving the apps from sd to the phone via menu-settings-applications-manage applications then reboot, move them back to sd and reboot again. Shot in the dark but its a thought.

[Q] Sd card filling up after flashing new roms.

Hi I looked to see if anyone else posted about this and I couldn't find one like this. I have an evo that I have rooted. I still have the 8gb sd card. After I rooted my phone I still had about 6gb left on my sd card. After I flashed Mikfroyo 4.5, reinstalled all my apps and and put most of my games on my sd card, like I had before I flashed mikfroyo I had about 4gb left on my sdcard. Yesterday I flashed a new rom on my phone, installed most of the apps that I had, and put the same amount of apps on my sd card it went down to under 2gb. I don't see triple the amount of folders on my sd card. Does anyone know why it shows up like this or at least how to free up some room? Thanks.

Have you been deleting the ROMs from your SD card after you flash them? Each Sense rom is roughly 180-200mb. It adds up. Also, if you have been creating Nandroid backups, they too will take up a lot Space, and you need to shuffle through them and delete the old ones. Nandroid backups add up quick. I don't store my apps on the SD card, so don't know much about it, but what method are you using to do so, and are you sure they're not doubling up? I'd be more suspicious of an excess amount of nandroid backups and roms on the sd card though. It doesn't take much to fill up that stock 8gb card.
i agree you should check how many nadroid backups you have on your card, they take a lot of room, i usually move them from my phone to my pc and only leave the last one on my phone, plus they are safer on the computer. also all the zip files you use to flash roms can be moved from the sd card to the computer, once used you dont need them on the root of your sd card anymore they just waste space, i would also recommend upgrading to a 16gb sd card ebay has them for like 20 to 30 bucks and save you the trouble of worrying about memory. to move files from one sd card to another you just connect phone to pc as disk drive open my pc and right click on the drive that represents your phone, go to folder options and in views, select view hidden files. once that is done just copy all inside the sd card to a folder on your pc. then you unplug from the computer, turn off phone replace old sd with new, turn on your phone go to settings storage and unmount the sd card then format it. the plug it to your pc again in disk drive open the folder where you put all the info from the old sd and copy all that to the drive your phone represents and hit yes when it says if you like to copy and replace some files, then you are done new sd and twice the memory cv

[Q] SD card suddenly not recognised and causing the phone to hang

Has this happened to anyone?
I am on GB. THe SD basically causes the phone to freeze when i try to access any of the settings. What are my options here? to reformat the card? i looked at the card on a laptop and the contents seemed ok. THe SD card is a sandisk Class 10 32GB card. I haven't installed any new apps for the past couple of weeks so i don't think this is a problem

I`d copy everything off the card to my hard drive , then reinsert the card into the phone and reformat it via the phone software , then let the phone set itself back up with the empty card and see if it works . But...that working around the issue (if it works) , the root cause I`d guess as a corrupted setting on the SD card . For the record , mine sometimes throws a stroppy (every couple of months) and says the card isnt there , the tried and tested turn off/on worked for me .
b/Have you copied any program across to the SD card ? I`d try copying them back to the phone

I know I'm pretty much screwed, but I'd figured I'd ask.....

Today, my 32GB SD card on my phone died today... so that means I have lost everything I had.. all my apps, backups, songs, saves on emulators, etc..
The SD card had to be broken and thrown in the trash, as it was not format-capable and was reading Blank SD Card constantly and my PC would not read it.
My only question now is, and it's a stretch but, ...if I get a new SD card, will I be able to SAVE ANY of what is on my phone now without an SD? My phone at current still shows icons from my SD card but tapping them leaves the App Not Installed, message.
Is it possible there's anything backed up the phone to actually TRANSFER sometime of the stuff on a new SD?

im sad to say that if the application was moved to the sd card it's near impossible to recover that specially if the sd card has been trown away, what you see are the icon traces which are saved in the system however the actual apk and other components on saved on the sd card can not be restored.
As far as I know, you guys are correct, the only way to find it would be in the /android-secure folder on the sd card.

Internal memory formatted SD card issues

I've an Samsung evo+ 256GB SD card formatted as internal storage in my HTC 10 for almost 2 years now.
2 months ago I decided to upgrade to a Samsung evo+ 256GB v2, with slightly better speeds. I simply cloned the old SD to the new one.
Everything was always fine, worked great till yesterday.
I had some weird stutters while playing music and then I noticed the UI was also getting stutterish.
Went to bed, charged my phone as I usually do. When I woke up and checked my mail the phone just froze and rebooted.
After reboot the phone told me the SD card was missing
I decided to shut down the phone and examine the SD card but the phone just got stuck shutting down, I had to force reboot and shutdown again.
I tested the SD by a full byte by byte read in Western Digital diagnostic tool for harddrives to see if my SD was broken, but it was fine, no errors.
I popped the SD back in my phone, started and the SD mounted fine, no issues so far.
Could the file system be corrupt? If it is, how do I fix it?
I could try and move the data to an external drive and reformat the SD, I've a USB 3 OTG cable. But I'm not sure how to do that either.
Will Android move the data for me automatically when removing the SD card as internal storage?
Stutters continued today unfortunately, especially when doing a SD benchmark.
I decided to use clonezilla and do a clone of the card to another one to see if that improves anything.
On the old SD I had 72MB/s read and 20MB/s write according to A1 SD bench
Internal storage 225MB/s read and 41MB/s write
On the cloned SD I have 74MB/s read and 19MB/s write
The difference is that the cloned SD is a Samsung evo+ 256GB v1 and the old one a Samsung evo+ 256GB v2
I don't get it though, doing a benchmark on a PC shows 90MB/s read and 80MB/s write.
I advice you to check media files. I had lived same problem. I found solution by chance . I attached sd card to my notebook to backup dcim and music folder. While copying the files, suddenly copy process stopped on a not special file. I removed the sd, re attached and deleted that file before continue to copy. When copying finished, i attached the sd card to phone... Whola... Without formatting or doing nothing extra the card started to work as expected
